IMPROVEMENT IN LOCKS EOR THE MEETING- RAIL OF SASHES.

The Schedule referred to in these Lettere Patent and making .part of the same.

We, FREDERICK W. JUDD and Gnonen M, HUB- Bunn, of the city and county of New Haven and State of Connecticut, have, invented cert-ain new and useful Improvements in Sash-Locks, ot' which the following is aspecitlcation.

Onrriuveution consists in the arrangement of a slotted spring lever, provided with a catch-pin upon the.

lower side of its handle end, and arranged with two plates having suitable notches in the edge of the saine, as hereinafter more fully described.

In the accompanying drawingllignres 1 and 2 are top views of a sash-loek ot' our invention, and

lfigure 3,21, side elevation of the saine, partly iu section.

A designates a portion of the upper, and

B, the lower window-sash.

C designates a plate secured to the open sash, and provided with notches, n. a, one at each end.

A lever, D, is pivoted tothe plate O by means of pin b passing through a slot, c, in lever D, so that said lever has a longitudinal as well as a swinging movement.

The back end of the lever D is hollow, so as to receive a sprng, d, which continually presses or holds the lever Vtoward its rear end. Y

The lever D is also provided with a handle, f, for operating said lever, and, immediately below said handle, is a catch-pin, 7L.

E designates a plate, which is secured to the top of the lower sash and provided with a notch, af.

To lock the sash the leverD is brought to the front, when the catch-pin h strikes the front edge ot' the plate E, and causes the lever to move end-wise on the pin b until the catch-pin comes opposite the notch a', when the spring l draws the catch-piu h. into the notch a', and, also, holds the upper and lower sash together, as well as locking the same Ain lthe usual manner, as shown in fig. 1.

It will be observed that the catch-pin It, resting in the notch af, will prevent the lever iiom beiug'turned to one side, and thus unlocked by means ot' any .thin implement inserted between the sashes.

When it is desired lto raise or lower` either sash, the lever D is pulled forward, so as to disengage the catolipin from the notch a', and then swung, either to the right or lett, until the catch-pin h is caught in one ot the notches a a in the plate O,A\vhich will hold said lever out of the way of the sash, as shown in lig. 2.

\Ve do not claim the lever D having both a swinging and longitudinal movement, as the same has been previously lused in a dil'ereltly arranged sash-lock.

\Ve claim as our invention- The arrangement of the catch-piu h upon the haudle end of tLe lever D, and the notches a a and a/ in the edge of the'plates C and E, the whole arranged and operating together substantially as described.
